Summary/Abstract: AI‐based language training has been shown to improve language proficiency among high school and similar language learners. In one study, a Duolingo intervention produced a 12% gain on tests of vocabulary, grammar, speaking, and writing compared with a 6% gain in a traditional setting. An intervention using an unspecified AI tool also led to better reading comprehension, gap filling, and matching outcomes. ChatGPT‐based training yielded large effect sizes (Cohen’s d = 0.76 – 0.88) in writing tasks, while a standardized vocabulary test reported significant gains (t = –18.186, p < 0.001). AI tools that feature gamification and personalized feedback tend to enhance student motivation. Studies report that adaptive apps such as GPT‐3.5, Speeko, and ELSA Speak increase intrinsic motivation, willingness to communicate, and overall engagement. Personalized AI features can enhance motivation and enjoyment in language learning, even without immediate vocabulary gains, highlighting their value in structured language programs.
